Should I have my car checked for poor fuel economy? Or are these numbers still ok?

[renzo_d10]

I don't turn off my engine on traffic kahit gano pa katagal idle niya. I only turn it off kapag mag-park ako or may i-pick up ako and I need to wait. On an everyday basis, using my 1.3 Vios MT, I get an average of 9km/L pure city driving. That includes an everyday battle with EDSA rush hour traffic and my travel is just 6-7kms one way. I hardly reach 5th gear (kapag dadaanan ko lang yung shortcut) since parati naman traffic.

What I'm saying is, given your conditions, I think your FC is just normal. AT pa sayo.

Siguro kapag lumamig yung panahon i-try ko yung patay makina kapag more than 1 minute yun stop. Hehehe. Then ill see the difference sa FC.

Another thing I've been observing btw are the Instant Fuel Consumption numbers on the Rio's Multi-Information Display.

When starting to accelerate from a full stop, the numbers are constantly around the 25-30L/100km mark, then when I feel the car shifting gears, bumababa siya to 20-25L/100km.

Only when I hit 3rd gear do the numbers start looking good, around 10-15L/100km, and even around the 5L/100km mark when coasting.

Pero for the 1st and 2nd gears, parang ang taas ng fuel consuption niya?

Its normal, your speed is slow, yet rpm is high, so fc increases. As you row thru the gears, speed increases, your rpm maintains, bababa fc. So save fc at 1st to 2nd gear, do gradual and slow starts, masisingitan ka nga lng. If i were u, take ayala, not buendia. Lighter traffic.

there is usually a considerable amount of "fine print" in these studies.. criteria.. conditions.. etc.. conditions that we may not fulfil if we drive "ordinary".
and yes, i also turn off my engine if i estimate at least 1 minute of standstill.

so, how does this affect my car maintenance? well, my besta's starter brushes had to be replaced at 50,000 km.. and my 1997 sentra's starter is still untouched after 14 years..

but hey! starter repair is cheap! it's not about hi tech electronics. it's low tech copper windings and brute force solid metal. "por kilo", 'eka nga..

btw, in heavy traffic, all fuel efficiency bets are off! how can you compete with 0 km/li ?

Starter wear on hot starts with an EFI car (versus a mechanical injection diesel) will be very low.

What wears a starter down is hard cranking due to cold oil, hard cranking due to low battery, excessive cranking due to unprimed carbs and etcetera.

Most starters are expected to last as long as the motor does, all things considered.

Wow mikmik, yang Nov 26 and Nov 29 fuel consumption mo ang regular fuel consumption ko. This is Pasig-Fort-Makati and back from around 6:30-8:00am and 5:30-8:00pm...

Almost pareho lang pala travel distance natin, TS. Kaya lang, almost 1.5 hrs on average lang ako round trip. FC ko around 9.0km/l naman with an Altis. Ang tagal mo stuck in traffic, kaya mukhang yan na nga talaga magiging FC mo. Since can be considered short distance ang 32km, baka pwede mag-motor ka na lang. Hehe.

[bong724]

mga master tanong ko lng bakit kaya nung after change oil parang tumaas yung FC ng everest namin, before change oil nsa 12km/liter FC nya but then nung kkachange oil lng halos 10.6km/l nlng sya? has anyone experience this situation??

After trying to come up stuff on my head, wala talaga ako alam na instance where oil will affect your mileage unless it's low or not of specification.

Drive like a grandma, bro. You'll be amazed sa fuel benefits at the expense of our ego machoness on the road

Same engine oil ba ginamit?

[bong724]

Same engine oil ba ginamit?

yun lang ang hindi ko alam sir, what if indi same engine oil ang ginamit sa previous na change oil? could it possibly affect the FC?
